Abstract The boron-vacancy spin defect ( $${\,{{\mbox{V}}}}_{{{\mbox{B}}}\,}^{-}$$ V B − ) in hexagonal boron nitride (hBN) has a great potential as quantum sensor two-di...

tetranychus urticae koch is an injurious pest of, fruit crops, crop plants as well as ornamental plants worldwide. the high reproductive potential of t. urticae and its fairly short life cycle along with the frequent application of acaricides usually required to maintain t. urticae populations below economic thresholds, facilitates the pest's resistance to acaricides, and consequently cont...

We report recurrent bacteremia due to mixed infection with two clonally derived isolates of Staphylococcus aureus in a patient with Sezary syndrome. The two isolates, one gentamicin resistant and methicillin susceptible and the other gentamicin susceptible and methicillin resistant, developed by the deletion of the mecA, ant(4')Ia, and aacA-aphD genes from a common gentamicin-resistant and meth...

resistance of 11 genotypes of sugar beet to cyst nematode was evaluated in two separate greenhouse experiments in completely randomized design. in each experiment, 50 seedlings of each genotype were inoculated with 1000 nematode larves in several times. after 9 weeks, the number of cysts on each plant was counted. data were analyzed with sas program. the results showed that the genotypes differ...

Purpose: To review some of the basic models, differential equations and solutions, both analytic numerical, which produce time courses for fractions Susceptible (S), Infectious (I) Recovered (R) population during epidemic and/or endemic conditions. Methods: Two three-compartment models with solutions to proposed linear as well based on non-linear first by Kermack McKendrick (KM) [1] a century a...

the process of adaptation to cold is an important mechanism in wheat cultivars to tolerate cold stress. this work was aimed to calrify the relationship between vernalization requirement with cold tolerance by assessing physiological changes in cold susceptible spring and tolerant winter wheat (triticum aestivum, cvs. kohdasht and cheyyene, respectively) in environmentally controlled conditions,...
